Can someone explain to me how these work ? They've always seemed to stay on an awfully long time before self cancelling, and sometimes now, they don't appear to self cancel at all (not the end of the world admittedly)
But, how do they work, is it on time, distance, or different depending on what speed you're doing ?
Can the settings be changed, or turned on or off?
